FIELD OF DISCLOSURE

Aspects of the present disclosure generally relate to use of computerhardware and/or software to manage data, and in particular to providingan organized data storage system.

BACKGROUND

Various methods of cryptography (e.g., encrypting and decrypting data)are known. Encryption may be associated with changing the data frombeing in a transparently readable format to being in an encoded,unreadable format with the help of an encryption algorithm. Decryptionmay be associated with changing the data from being in the encoded,unreadable format to being in the transparently readable format with thehelp of a decryption algorithm. Encoded/encrypted data may bedecoded/decrypted with a given decryption key. In an example, symmetriccryptography may utilize encryption and decryption algorithms that relyon a single private key for encryption and decryption of data. Symmetriccryptography is considered to be relatively speedy. One example of anencryption and decryption algorithm utilized by symmetric encryption maybe an AES encryption cipher. On the other hand, asymmetric cryptographymay utilize encryption and decryption algorithms that rely on twoseparate but mathematically-related keys for encryption and decryptionof data. For instance, data encrypted using a public key may bedecrypted using a separate but mathematically-related private key. Thepublic key may be publicly available through a directory, while theprivate key may remain confidential and accessible by only an owner ofthe private key. Asymmetric encryption may also be referred to as publickey cryptography. One example of an encryption and decryption algorithmutilized by asymmetric encryption may be Rivest-Shamir-Adleman (RSA)protocol.

The system 100 includes one or more userdevices 102 communicating a stateless infrastructure 110 including aprocessing unit 112 and a database (e.g., memory) 114. In an example, auser device 102 may include a processing unit 106 and may utilize aninstalled client application 104 to communicate with an applicationprogramming interface (API) (not shown) included in the statelessinfrastructure 110. In some aspects, the user device 102 and thestateless infrastructure 110 may communicate with one another over anetwork 120. The network 120 may be wired or wireless network. In someaspects, the network 120 may include one or more of, for example, aphone line, a local-area network (LAN), a wide-area network (WAN), ametropolitan-area network (MAN), a home-area network (HAN), Internet,Intranet, Extranet, and Internetwork. In some aspects, the network 120may include a digital telecommunication network that permits severalnodes to share and access resources.

The user device 102 may be a physical computing device capable ofhosting a client application and of connecting to the network 120. Theuser device 102 may be, for example, a laptop, a mobile phone, a tabletcomputer, a desktop computer, a smart device, a router, or the like. Insome aspects, the user device 102 may include, for example,Internet-of-Things (IoT) devices such as VSP smart home appliances,smart home security systems, autonomous vehicles, smart health monitors,smart factory equipment, wireless inventory trackers, biometric cybersecurity scanners, or the like. The user device 102 may include and/ormay be associated with a communication interface to communicate (e.g.,receive and/or transmit) data.

In some aspects, the stateless infrastructure 110 may provide the userdevice 102 with a client application 104 to be installed on the userdevice 102. The client application 104 may enable a processor (e.g.,processing unit 106, processor 520) associated with the user device 102to encrypt and decrypt the data. In some aspects, the client application104 and/or the stateless infrastructure 110 may utilize one or moreencryption and decryption algorithms to encrypt and decrypt the data.The encryption algorithms and decryption algorithms may employ standardssuch as, for example, data encryption standards (DES), advancedencryption standards (AES), Rivest-Shamir-Adleman (RSA) encryptionstandard, Open PGP standards, file encryption overview, disk encryptionoverview, email encryption overview, etc. Some examples of encryptionalgorithms include a triple data encryption standard (DES) algorithm,Rivest-Shamir-Adleman (RSA) encryption algorithm, advanced encryptionstandards (AES) algorithms, Twofish encryption algorithms, Blowfishencryption algorithms, IDEA encryption algorithms, MD5 encryptionalgorithms, HMAC encryption algorithms, etc.

In some aspects, data may include any information such as privateinformation including, for example, bank account numbers, credit cardnumbers, various passwords, etc. In some aspects, the data may includeelectronic information included in files such as, for example,photographs, documents, compact discs (CDs), digital video disks (DVDs),etc. including written, printed, and/or electronic matter that providesinformation and/or evidence.

The stateless infrastructure 110 may include the processing unit 112 andthe database 114. The processing unit 112 may include a logicalcomponent configured to perform complex operations to evaluate variousfactors associated with encrypting and decrypting the data. The database114 may store various pieces of information associated with encryptingand decrypting the data, including encrypted content and/or encryptedkey information. In some aspects, the stateless infrastructure 110 mayinclude an application programming interface (API) (not shown) tocommunicate with the client application 104. The statelessinfrastructure 110 may include or be associated with a communicationinterface to communicate (e.g., transmit and/or receive) data.

As indicated above, FIG. 1 is provided as an example. Other examples maydiffer from what is described with regard to FIG. 1 .

A user device may request data storage services from a data storageservice provider (DSSP). Such data storage services may include cloudstorage services that enable the user device to utilize, for example,the Internet to store data on remote servers and/or storage devicesmanaged by the DSSP. The data storage services may also be referred toas cloud backup services, online data storage services, online drivestorages, file hosting services, file storage services, or the like. TheDSSP may attempt to protect the stored data by requiring the user deviceto provide credentials (e.g., username, password, one-time passwords,one-time tokens, or the like) to gain authorized access to the storeddata. The data storage services may be available via use of a webinterface and/or an application interface.

In some instances, the DSSP may fail to protect the stored data. In anexample, a third party may gain unauthorized access to the stored databy, for example, hacking into the servers and/or storage devices managedby the DSSP. In another example, internal devices associated with theDSSP that have access to the servers and/or storage devices managed bythe DSSP may gain unauthorized access to the stored data. As a result,an integrity associated with the stored data may be compromised. Toregain access to the stored data and/or to protect the stored data, theuser device and/or the DSSP may expend resources (e.g., managementresources, memory resources, computational/processing resources, powerconsumption resources, system bandwidth, network resources, etc.) thatmay otherwise be used for more suitable tasks associated with the datastorage services.

Various aspects of systems and techniques discussed in the presentdisclosure are associated with encrypting and data. In some aspects, aDSSP may provide a stateless system including a stateless infrastructureand/or a client application installed on a user device. In some aspects,the stateless infrastructure may provide the user device with the clientapplication. In some aspects, the client application may enable the userdevice to encrypt and decrypt the data that the user device may wish toprotect. In an example, the client application may enable the userdevice to encrypt data, to store the encrypted data, and to decrypt theencrypted data. In some aspects, the user device may encrypt the data,store the encrypted data, and decrypt the encrypted data without thestateless infrastructure having access to and/or storing unencrypteddata. As a result, even if a third party gains unauthorized access tothe client application and/or the stateless infrastructure, theunauthorized access may lead to encrypted data, which the third partymay not be able to decrypt. The client application and/or the statelessinfrastructure may employ a particular arrangement of keys to encryptand decrypt the data. Such particular arrangement of keys may becritical because it enables the client application and/or the statelessinfrastructure to provide data storage services (e.g., protect storeddata) without storing unencrypted data. In this way, the clientapplication and/or the stateless infrastructure may mitigate instancesof the data becoming compromised, thereby enabling efficient utilizationof resources (e.g., management resources, memory resources,computational/processing resources, power consumption resources, systembandwidth, network resources, etc.) associated with the user deviceand/or the stateless infrastructure for more suitable tasks related tothe data storage services.

Additional aspects of systems and techniques discussed herein enable thestateless system to provide the organized data storage system. In someaspects, the stateless system may provide virtual folders and may enableauthorized access to the virtual folders and prevent unauthorized accessto the virtual folders. In some aspects, as discussed below in furtherdetail, the stateless system may provide one or more relationships usinga particular key arrangement. Such particular key arrangement may becritical because it enables authorized access to the virtual folders andprevents unauthorized access to the virtual folders without havingaccess to unencrypted data. In some aspects, the virtual folders mayinclude encrypted content.

In some aspects, the stateless system (e.g., client application and/orthe stateless infrastructure) may determine an assigned key pairincluding an assigned public key and an assigned private key; determine,for a folder including encrypted content, a folder access key pairincluding a folder access public key and a folder access private key;encrypt the folder access private key by utilizing the assigned publickey; and access the encrypted content based at least in part ondecrypting the folder access private key.

FIG. 2 is an illustration of an example flow 200 associated withproviding an organized data storage system, according to various aspectsof the present disclosure. The example flow 200 may include a userdevice 102 in communication with a stateless infrastructure 110. In someaspects, the user device 102 may install a client application 104associated with the stateless infrastructure 110 and may use the clientapplication 104 to communicate with an application programming interface(API) and a processor (e.g., processing unit 112, processor 1020)associated with the stateless infrastructure 110. In some aspects, theuser device 102 and the stateless infrastructure may communicate over anetwork (e.g., network 120).

As shown by reference numeral 210, the user device 102 may register anaccount with the stateless infrastructure 110. In some aspects, duringthe registration, the user device 102 may provide registrationinformation such as, for example, identity of an owner of the userdevice 102, a phone number associated with the user device 102, an emailaddress associated with the user device 102, or the like. In someaspects, the user device 102 may set up an access system including, forexample, username, password, or the like to subsequently gain access tothe registered account.

In some aspects, the stateless infrastructure 110 may provide the clientapplication 104 to be installed on the user device 102. The clientapplication 104 may enable the user device 102 to receive information tobe processed by the client application 104 and/or by the statelessinfrastructure 110. The client application 104 may include a graphicalinterface to receive the information via a local input interface (e.g.,touch screen, keyboard, mouse, pointer, etc.) associated with the userdevice 102. The information may be received via text input or via aselection from among a plurality of options (e.g., pull down menu,etc.). In some aspects, the client application 104 may activate and/orenable, at a time associated with the registration (e.g., after theregistration), the graphical interface for receiving the information.For instance, the client application 104 may cause a screen (e.g., localscreen) associated with the user device 102 to display, for example, apop-up message to request entry of the information. Further, the clientapplication 104 may enable transmission of at least a portion of theinformation to the stateless infrastructure 110.

As shown by reference numeral 220, the stateless system may determineinformation based at least in part on the registration of the accountwith the stateless infrastructure 110. In an example, the clientapplication 104 may determine an asymmetric assigned key pair for theregistered account associated with user device 102. The assigned keypair may be unique to the registered account and may include an assignedpublic key and an assigned private key. In this way, the assigned publickey and the assigned private key may be account-specific and/or maybeassociated with the registered account. In some aspects, the assignedpublic key and the assigned private key may be associated with eachother via, for example, a mathematical function. As a result, dataencrypted using the assigned public key may be decrypted by utilizingthe assigned private key.

Further, the client application 104 may receive a master string ofalphanumeric characters from the user device 102. In some aspects, themaster string may be unique and be associated with the registeredaccount associated with the user device 102. Based at least in part onreceiving the master string, the client application 104 may determine amaster key. In some aspects, the client application 104 may utilize apassword derivation function and/or a key derivation function todetermine the master key based at least in part on the master string.The password derivation function and/or the key derivation function mayperform password hashing to determine the master key. The clientapplication 104 may utilize the master key to encrypt the assignedprivate key associated with the registered account.

As shown by reference numeral 230, the client application 104 maytransmit, and the stateless infrastructure 110 may receive, at least aportion of the information determined by the client application 104. Forinstance, the client application 104 may transmit, for example, theassigned public key and the encrypted assigned private key to thestateless infrastructure 110. The stateless infrastructure 110 may storeand correlate the received information in association with theregistered account associated with the user device 102. In some aspects,when another device associated with the registered account (e.g.,another device owned by and/or available to the owner of the user device102) wishes to decrypt the encrypted content, the statelessinfrastructure 110 may provide such information to the other device.

In some aspects, the stateless system may provide one or more folders.In an example, the client application 104 may enable the user device 102to associate (e.g., store) the one or more folders locally and/orremotely. In an example, the user device 102 may provide the one or morefolders in association with a local memory and/or a remote memoryassociated with the user device 102. In another example, the user device102 may provide the one or more folders in association with a database(e.g., database 114) associated with data storage services provided bythe stateless system. In yet another example, the user device 102 mayprovide the one or more folders in association with a hand-held memory(e.g., a USB thumb drive, flash drive, etc.). In some aspects, the userdevice 102 may provide a folder based at least in part on storing, in amemory, data (e.g., information, encrypted content, etc.) within and/orin association with the folder. In some aspects, the one or more foldersmay include one or more virtual folders. A virtual folder may include,for example, a pointer to indicate a location of the data and/orinformation (e.g., a “shortcut”) indicating a path to the location ofthe data.

For a given virtual folder, as shown by reference numeral 240, theclient application 104 may determine a folder access key pair. Thefolder access key pair may include a folder access public key and afolder access private key. The folder access public key and the folderaccess private key may be associated with each other via, for example, amathematical function. As a result, data encrypted using the folderaccess public key may be decrypted by utilizing the folder accessprivate key. Further, the client application 104 may encrypt the folderaccess private key by utilizing the assigned public key associated withthe registered account.

As shown by reference numeral 250, the client application 104 maytransmit, and the stateless infrastructure 110 may receive, at least aportion of the information determined by the client application 104. Forinstance, the client application 104 may transmit the folder accesspublic key and the encrypted folder access private key to the statelessinfrastructure 110. In some aspects, when another device associated withthe registered account (e.g., another device owned by and/or availableto the owner of the user device 102) wishes to access the virtualfolder, the stateless infrastructure 110 may provide such information tothe other device.

When the user device 102 (or the other device associated with theregistered account) may wish to access the virtual folder, the userdevice 102 (e.g., or the other device) may access the registered accountand request the encrypted assigned private key from the statelessinfrastructure 110. Based at least in part on receiving the request, asshown by reference numeral 260, the stateless infrastructure 110 maytransmit, and the client application 104 may receive, the encryptedassigned private key. In some aspects, as shown by reference numeral270, the stateless infrastructure 110 may transmit additionalinformation such as, for example, the encrypted folder access privatekey, location of the virtual folder, etc. when the user device 102and/or the other device may not have access to such additionalinformation.

Based at least in part on receiving the encrypted assigned private key,the encrypted folder access private key, etc., the client application104 may be enabled to access the virtual folder. In an example, theclient application 104 may request entry of the master string and basedat least in part on receiving the master string, the client application104 may determine the master key that was utilized to encrypt theassigned private key. The client application 104 may utilize the masterkey to decrypt the assigned private key. The client application 104 mayutilize the assigned private key to decrypt the encrypted folder accessprivate key based at least in part on an association between theassigned private key and the assigned public key. Further, the clientapplication 104 may utilize the access private key to access the virtualfolder. In some aspects, the client application 104 may utilize theaccess private key to access encrypted content associated with and/orincluded within the virtual folder.

In some aspects, one or more functionalities performed by the clientapplication 104 may be included in and/or may be performed by thestateless infrastructure 110, and vice versa.

In someaspects, the user device 102 may install a client application 104associated with the stateless infrastructure 110 and may use the clientapplication 104 to communicate with an application programming interface(API) and a processor (e.g., processing unit 112, processor 520)associated with the stateless infrastructure 110. In some aspects, theuser device 102 and the stateless infrastructure may communicate over anetwork (e.g., network 120).

In some aspects, the user device 102 may wish to encrypt data and tostore the encrypted data. As discussed below with respect to FIG. 4 ,the user device 102 may wish to encrypt data and to store the encrypteddata within and/or in association with a virtual folder. In someaspects, the client application 104 may determine respective symmetrickeys and content access key pairs for each piece of data (e.g., content)that the user device 102 may wish to encrypt. In this way, the symmetrickey and the content access key pair may be content-specific. Examples ofcontent may include any information including, for example, alphanumericdata such as passwords, credit card numbers, bank account numbers, etc.and/or information that is written, printed, and/or electronicallyincluded in documents and/or files such as photographs, or processingdocuments, CDs, DVDs, etc.

For given content, as shown by reference numeral 310, the clientapplication 104 may utilize a random bit generator to determine asymmetric key. In an example, the symmetric key may be a random keyincluding a sequence of unpredictable and unbiased information. Further,the client application 104 may determine a content access key pairincluding a content access public key and a content access private key.The content access public key and the content access private key may beassociated with each other via, for example, a mathematical function. Asa result, data encrypted using the content access public key may bedecrypted by utilizing the content access private key.

The client application 104 may utilize the symmetric key and the contentaccess key pair to encrypt the content. In an example, the clientapplication 104 may encrypt the content access private key using theassigned public key associated with the registered account (e.g., firstencryption of content access private key). The client application 104may encrypt the symmetric key by utilizing the content access publickey. The client application 104 may encrypt the content by utilizing thesymmetric key. In some aspects, the client application 104 may enablethe user device 102 to store the encrypted content.

As shown by reference numeral 320, the client application 104 maytransmit, and the stateless infrastructure 110 may receive, at least aportion of the information determined by the client application 104. Forinstance, the client application 104 may transmit one or more of thecontent access public key, the encrypted content access private key, theencrypted symmetric key, or the encrypted data to the statelessinfrastructure 110. In some aspects, when another device associated withthe registered account (e.g., another device owned by and/or availableto the owner of the user device 102) wishes to decrypt the encryptedcontent, the stateless infrastructure 110 may provide such informationto the other device.

When the user device 102 (or the other device associated with theregistered account) may wish to decrypt the encrypted content, the userdevice 102 (e.g., or the other device) may access the registered accountand request the encrypted assigned private key (discussed with respectto FIG. 2 ). Based at least in part on receiving the request, as shownby reference numeral 330, the stateless infrastructure 110 may transmit,and the client application 104 may receive, the encrypted assignedprivate key. In some aspects, as shown by reference numeral 340, whenthe user device 102 and/or the other device may not have access to theencrypted content, the stateless infrastructure 110 may also transmitthe first encrypted content access private key, the encrypted symmetrickey, and the encrypted content to the user device 102 and/or the otherdevice.

Based at least in part on receiving the encrypted assigned private key,the encrypted content access private key, the encrypted symmetric key,and/or the encrypted content, the client application 104 may be enabledto decrypt the content. For instance, the client application 104 mayrequest entry of the master string and based at least in part onreceiving the master string, the client application 104 may determinethe master key that was utilized to encrypt the assigned private key(discussed above with respect to FIG. 2 ). The client application 104may utilize the master key to decrypt the assigned private key. Theclient application 104 may utilize the assigned private key to decryptthe encrypted content access private key based at least in part on anassociation between the assigned private key and the assigned publickey. Further, the client application 104 may utilize the content accessprivate key to decrypt the symmetric key based at least in part on anassociation between the access private key and the access public key. Asshown by reference numeral 350, the client application 104 may utilizethe symmetric key to decrypt the content. In this way, the user device102 (and/or the other device) may directly access the content.

In some aspects, one or more functionalities performed by the clientapplication 104 may be included in and/or may be performed by thestateless infrastructure 110, and vice versa.

As indicated above, FIG. 3 is provided as an example. Other examples maydiffer from what is described with regard to FIG. 3 .

FIG. 4 is an illustration of an example flow 400 associated withproviding an organized data storage system, according to various aspectsof the present disclosure. The example flow 400 may include a userdevice 102 in communication with a stateless infrastructure 110. In someaspects, the user device 102 may install a client application 104associated with the stateless infrastructure 110 and may use the clientapplication 104 to communicate with an application programming interface(API) and a processor (e.g., processing unit 112, processor 520)associated with the stateless infrastructure 110. In some aspects, theuser device 102 and the stateless infrastructure may communicate over anetwork (e.g., network 120).

In some aspects, the user device 102 may wish to store encrypted contentwithin and/or in association with a virtual folder. In this case, thestateless system may enable provision of a relationship between theencrypted content and the virtual folder. In some aspects, therelationship may utilize a particular key arrangement. Such particularkey arrangement may be critical because, without having access tounencrypted data, the stateless system enables authorized access to theencrypted content via the virtual folder and prevents unauthorizedaccess to the encrypted content via the folder.

To provide the relationship between given encrypted content and thevirtual folder, as shown by reference numeral 410, the clientapplication 104 may again encrypt the content access private keyassociated with the encrypted content by utilizing the folder accesspublic key associated with the virtual folder (e.g., second encryptionof content access private key).

As shown by reference numeral 420, the client application 104 maytransmit the second encrypted content access private key to thestateless infrastructure 110. In some aspects, when another deviceassociated with the registered account (e.g., another device owned byand/or available to the owner of the user device 102) wishes to decryptthe encrypted content via access to the virtual folder, the statelessinfrastructure 110 may provide such information to the other device.

When the user device 102 (or the other device associated with theregistered account) may wish to decrypt the encrypted content via accessto the virtual folder, the user device 102 (e.g., or the other device)may access the registered account and request the encrypted assignedprivate key (discussed with respect to FIG. 2 ). Based at least in parton receiving the request, as shown by reference numeral 430, thestateless infrastructure 110 may transmit, and the client application104 may receive, the encrypted assigned private key. In some aspects, asshown by reference numeral 440, when the user device 102 and/or theother device may not have access to the encrypted content, the statelessinfrastructure 110 may also transmit the second encrypted content accessprivate key, the encrypted symmetric key, and the encrypted content tothe user device 102 and/or the other device.

Based at least in part on receiving the encrypted assigned private key,the second encrypted content access private key, the encrypted symmetrickey, and/or the encrypted content, the client application 104 may beenabled to decrypt the content via access to the virtual folder. Forinstance, the client application 104 may request entry of the masterstring and based at least in part on receiving the master string, theclient application 104 may determine the master key that was utilized toencrypt the assigned private key (discussed above with respect to FIG. 2). The client application 104 may utilize the master key to decrypt theassigned private key.
